Persisting a Drools Knowledge Session

Is it possible to persist a Knowledge Session in Drools? If so, how? I have facts stored in a database and i'd like to avoid reloading all of them in a new session everytime a new fact is added. At the moment, when there's a new fact, the fact is stored in the database and then Drools is called: it loads all facts in its session and then fires the rules. The session is lost between calls.

Yes, you can persist sessions to any "binary stream", i.e., files, databases, your in-memory cache, etc. You can also use JPA to manage the persistence for you. Documentation:
